This invention is a heater of the type in which a gas flame is utilizedas the initial source o fheat.

One of the objects of the invention is to provide a heater equipped withagas burner located as nearly as may be at the focal position withrespect to a circular'concaved reflector, so that a highly eflicientdispersion of heat rays will be obtained by means of n uniformreflection of rays. A further object is to provide a gas heater of thecharactor mentioned having means for magnifying or increasing the heatproducing capacity of the gas flame which would normally be produced bya gas burner. A further object is to provide simple means foreiiiciently supporting the parts in position, so that they 2 may bereadily assembled or dismantled as occasion may require. A furtherobject is 20 to provide means. by which the'parts may be adjusted toinsure a proper combustible mix-' ture so as to compensate for varyingcond1- tions due to changes in the quality of gas being consumed. I Y IThe, invention will be hereinafter fully set forth and particularlypointed out in the claims:}

In theaccomp'anying drawings I Figure 1 is a longitudinal sectional viewof a heater constructed in accordance with the invention. Figure 2 is anenlarged detail View illustrating the burner section and the burner jetin assemble'd relation. Figure 3 burner-tip retaining cap. Figure 4 is afront view illustrating the burner tip. 7

Referring to the drawings, 10 designates a concavo-convexreflector'constructed of any suitable material, and provided with a 40central opening 11. Secured to the outer face of said reflector, nearone edge is alug 12,- which is-pivotally mounted between ears 13,projecting upwardly from abase- 14-.

.13 designates a burner section .which' is 4 constructed of a tubulardischarge member is an enlarged detail view illustrating the 15 and anexternally threaded tubular stem 16 of reduced diameter. The front endof the stem 16 removably engages the contiguous threaded end of thelarger section 15, so as to provide an annular shoulder 17 Said tubularstem 16 is also provided near its inlet end -with air inlet slots 18.The tubular stem 16 is also provided with an internal screw thread toberemovably engaged with a 7 corresponding externally threaded portion'ofa jet member 19, which is provided with a cook 20 by means of which theflow of gas through the jet and the burner section may be controlled.The inlet end of said jet member 19 is connected in suitable manner witha gas sired construction; v

The burner section is secured in position bypassing the tubular stem 16rearwardly through the hole 11, fromthe front of the reflector, untilthe shoulder 17 abuts against the reflector. A nut 22, working on thesupply tube 21 of any destem 16 is then screwed up so as to firmly clampthe reflector 10 between it and the said shoulder 17 By thisarrangement, the burner section is rigidlyheld in'position, and may bequickly removed if necessary.

An; air supply chamber is provided by means of a cap 23, having anopening through which thetubular stem 16 is eX- tended, and said cap isheld in position with its edge abutting against the back of thereflector, by meansof a nut 24, as clearly shownin Figure 1. Saidcap isprovided with air inlet openings 25.

The burner tip consists of a disk 26'of re? fractory material, providedwith a plurality of perforations through which the combustible mixtureisdischarged so as to be ignited. Said disk is retainedin position bymeans of a sleeve 27 which extends over and enretain the disk in place.vided with a lug 29.

Enclosing the cap 26 and the contiguous portions of the burner sectionis a heat intensifying member H, consisting of a body of refractorymaterial provided with a cylindrical hub-like portion 80, and a conicalportion 31 flaring outwardly from said sleeve portion. Said conical bodyis provided with perforations 32 of varying sizes, the perforations inthe lower portion thereof being larger than those in the upper portion.Said intensifier is retained in position by sliding the hub 30 over thesleeve 27, and in order to prevent rotation thereof, the hub 30 isprovided with a longitudinal groove to engage the lug 29. V

In practice, the burner section B, the cap 23 and the burner et areassembled and secured in position upon the reflector in the manneralready described, and the heat intensifler H is then secured inposition. hen it is desired to utilize the heater, the cock 20 is openedand gas from asuitable Said cap is prosource of supply enters the burnersection through the jet 19 and tube 15 and the section 16, air enteringsaid tube 15 through the slots 18, reaching said slots from the outsideatmosphere through the openings 25. It is to be understood, of course,that the relative position of the jet 19 with respect to the burner tip26 has first been adjusted to produce the proper mixture and flow of gassuitable to the particular gas supply being drawn upon. ture isdischarged through the perforations in the disk 26, it passes out of theperforations 32 in the heat intensifier and may be readily ignited. Thecombustion of the mixture at the burner jet 28 raises the temperature ofthe intensifier H and in a very short time said intensifier is heated toincandescence and the heat rays emanating therefrom will impinge againstthe reflector 10, and by reason of the shape of the latter will bedirected forwardly into the space to be heated. By making the openings32 larger in the lower part of the intensifier and smaller in the upperpart, a freer outlet for the burned gases is provided at the lowerportion of the burner than at the upper portion thereof and thedistribution of the heat around, and through the refractory materialofthe intensifier is rendered more uniform and efficient. It will benoted that the enlarged portion 31 of the intensifier H extendsapproximately to the plane of the peripheral edge of the reflector, sothat the intense heat produced thereby will not in any way injure thematerial of which-the reflector is constructed.

The advantages of the invention will be readily understood by thoseskilled in the art to which it belongs. For instance, a very importantadvantage is that the refractory As the combustible mlxheat intensifieris positioned as nearly as possible at the focal point of the reflector,and the heat produced by the incandescence of said jacket is thereforeuniformly distributed and projected into the space to be heated. Byenclosing the burner tip within a refractory jacket, the efficiency ofthe burner is greatly increased because the normal heat-producingcapacity of the gas flame is greatly magnified by the incandescence ofthe refractory material. Another important advantage is that the burnertube, burner jet and burnertip are all so related and constructed thatthey may be readily assembled or dismantled as occasion may require, andthey may also be quickly secured to or detached from the reflector.
